a real-world study of lamivudine and dotiravir sodium tablets in the treatment-naïve hiv-1 infected patients

Conditions: HIV-1-infection

Summary: actual update to the us department of health and human services treatment guidelines for hiv-1 infection and european aids clinical society guidelines indicate dovato(dolutegravir/lamivudine) as an initial treatment in hiv-naïve patients. however there is no real- life data. the investigators' results in real life have encouraged us to conduct a multicenter cohort study in patients who have already started their first antiretroviral therapy with dtg (dolutegravir) + 3tc(lamivudine ), to verify efficacy and tolerance in real life. the investigators' hypothesis is that the data will be similar to those reported in clinical trials.

since 1996, haart(highly active antiretroviral therapy) based on 3dr(3-drug regimens ) in plhiv(people living with hiv) has decreased mortality and today, plhiv have a life expectancy close to that of the general population. in the last decade new drugs have improved tolerance and posology of these treatment. however plhiv needs to continue the treatment and will likely remain on antiviral therapy for many years. in the recent period, active research is being sought with the aim of improving the dosage and reducing the amount of drugs necessary to maintain efficacy, to avoid the possible cumulative effects of long-term art (antiretroviral therapy). 2drs(two-drug regimens) have been investigated as a means for reducing the number of arvs(antiretroviral agents) taken by individuals who need lifelong art. dovato has been evaluated in two phase iii studies (gemini-1 and gemini-2) in treatment-naive adults achieving non inferiority according to the us fda (food and drug administration) snapshot algorithm. these data led to the approval of the fixed-dose combination of dolutegravir/lamivudine as a once-daily, single-tablet 2dr by the fda and the european medicines agency. actual update to the us department of health and human services treatment guidelines for hiv-1 infection and european aids clinical society guidelines indicate dovato as an initial treatment in hiv-naïve patients. however there is no real- life data. the investigators' aim is to provide information related to effectiveness and tolerability/safety in naïve patients when used in routine clinical practice. it has been already published results from the phase iii study in pretreatment adult patients. the investigators' results in real life have encouraged us to conduct a multicenter cohort study in patients who have already started their first antiretroviral therapy with dtg (dolutegravir) + 3tc(lamivudine ), to verify efficacy and tolerance in real life. the investigators' hypothesis is that the data will be similar to those reported in clinical trials.
